I've seen that happen on cars that the distributor was either stabbed 180* out or wired backwards (ala clockwise instead of counter on the cap)

something is causing pressure in the crankcase....
Clogged PCV valve usually results in the dipstick blowing out....along with copius amounts of oil! DAMHIK!

I've had it happen a couple times, personally I'm wondering if felpro is sneaking a couple thou here and there of metal off them and they've gotten weaker over time.....

You had a little back fire just didn't notice/hear it when it happened. I'd say you're good.

Again .. the last time I saw one of these VP's that did this .... there was a hole in the piston almost the size of a quarter.
I certainly hope not. But I doubt there is any real damage to anything internal. The idle is exactly the same and there is absolutely no change in drivability and it still hauls ass, ha ha!!

It may have just been an un-heard backfire, but would be a good idea to check compression to be sure. May not be a problem if the engine is running fine. P.S.: A "Pan-Evac" is a Crankcase Evacuation System. Basically, a 1/2-inch pipe, cut at a 45-degree angle, inserted/welded into your header-collector. A check-valve is screwed onto the threaded-end of the pipe, and hose connects check-valve to closed-type crankcase breathers. The pipe, placed in the exhaust stream, draws air from the crankcase, causing a partial vacuum, reducing crankcase pressure, removing blow-by, improving windage. Sort of a poor-mans crankcase vacuum pump. Pan Evac Kit

I've seen a bad fuel pump cause this. Gas gets pumped into the crankcase, ignites, ballooning the valley pan, valves covers and even the oil pan. It you're running a mechanical fuel pump you may want to take a look at it. Does your oil smell like gas?
I love the smell of Deer guts in the morning, it smells like... VICTORY!

I use a block off plate, no pump. Only an electric.

Actually, it is supposed to be a closed-system. The breathers included in the kit are used (or similar if you want something else.)
The kit also includes grommets to seal the breathers to the valve covers.
Serious race engines (some street engines too) use crankcase vacuum pumps (if legal per the controlling sanctioning body) to remove the air and extraneous combustion gasses, etc, from the crankcase.
This provides better ring seal, but in addition, removing the air improves horsepower, as the back sides of the pistons do not need to move air around inside the crankcase.
You think about the air above the piston (air/fuel mixture) but there is also air inside the crankcase below each piston that has to be displaced/moved around, energy being expended in the process. Also, there is less wind resistance for the crank to spin around as well.
A Pan Evac provides some of these same benefits to a much lesser degree, but still helps.
I use both the Pan Evac and PCV on the 440 in my '71 Charger and even the AMC 304 V8 in my CJ-5 Jeep.

Id say you have blowby in the motor.My 440 and the kids original 62 413 run just 2 breathers.His gets tons of miles daily.Never had one pop up.Rocky

Now that would have to be some fuel-rich oil to do that !! PLUS ... oil diluted that badly .. the bearing would be hurt by that fact.
